Descriptions


Fly.io


Fly is an opensource runtime for edge apps, Fly offers a paid hosted version of their product as well. This provider will focus on the paid hosted version. Fly.io is one of the few companies and products that has a full range of tools alongside their actual product, which makes them an ideal candidate for curious developers and new companies to experiment.

Everything they do is docker based, and their networking abstraction is top notch, it’s clear Fly will play a major role in turning the space into a more user-friendly one. Fly’s ambitious mission to make application distribution as ubiquitous as CDNs sets the bar for any contenter willing to compete.
